Thanks, there is a guy at the field with a few of them. Actually the club pres. He swears by them and
has a new plane all the time with one on it. But when he flies I notice they hesitate or cough and then
go. Maybe its how they are tuned and he likes them that way.

I am considering these because I am tired of the heavy super tigre mufflers, if you want to buy a
aftermarket muffler they are about 30 dollars. So that would put the motor at about $100 for a
40ish size. That is rediculious, I will consider a 4 stroke before I would do that.
